Description
Technical field: the utility model relates to a kind of gas heater air jet pipe body structure, refers more particularly to the air jet pipe body structure in a kind of burner that is applicable to gas heater.
Background technology: in the prior art, gas heater adopts cubic copper pipe and subsection-inlet copper pipe to be welded with the air jet pipe body structure, and the two ends of jet body seal by seal cover, and the welding procedure difficulty of processing is big, and the copper material costliness; The air jet pipe body structure that also has adopts pack alloy to cast out jet body, inlet body by mould, the two ends of jet body and the port of inlet body all adopt the seal cover sealing, inlet body is assemblied on the jet body by the seal washer sealing, very hard during assembling, and sealing is poor, causes gas leak phenomenon easily.For overcoming these defectives, gas heater is developed with the air jet pipe assembly structure.
Summary of the invention: technical problem to be solved in the utility model is that a kind of gas heater air jet pipe body structure will be provided, and it has the sealing that improves air jet pipe effectively, reduces cost and is convenient to characteristics such as assembling.
The technical scheme that its technical problem of solving the utility model adopts is: it comprises jet body, is used for installing the control valve of gas heater air jet pipe assembly transition components, spring and autumn air inlet pipe, winter air inlet pipe, described spring and autumn air inlet pipe and winter air inlet pipe an end communicate with jet body, the other end communicates with an end of control valve, the other end of control valve communicates with jet body, it is characterized in that described spring and autumn air inlet pipe, winter air inlet pipe, jet body and control valve are one of the forming.
Described spring and autumn air inlet pipe, winter, air inlet pipe, jet body and control valve were cast as one by die casting.
Described control valve comprises first control valve, second control valve, and the inwall of first control valve is provided with the air admission hole in summer that communicates with jet body, and an end of second control valve communicates with first control valve, and the other end is provided with seal cover.
Described spring and autumn air inlet pipe and winter air inlet pipe be positioned at the both sides of second control valve and be staggered.
Described spring and autumn air inlet pipe and winter air inlet pipe be parallel to each other.
The inwall of described second control valve is provided with metallic sheath.
The utility model is compared the beneficial effect that is produced with prior art: since the utility model adopt jet body, spring and autumn air inlet pipe, winter air inlet pipe and control valve be the integrally formed structure of die casting, dying, it can improve the sealing of air jet pipe effectively, reduce cost, and is convenient to assembling.
Description of drawings: Fig. 1 structural representation of the present utility model.
Fig. 2 is Fig. 1 profile.
Fig. 3 is the connection diagram of transition components 13 in Fig. 1 and the gas heater air jet pipe assembly.
The specific embodiment: shown in accompanying drawing 1, accompanying drawing 2, the utility model comprises jet body 1, spring and autumn air inlet pipe 6, winter air inlet pipe 10 and be used for installing the control valve 15 of gas heater air jet pipe assembly transition components 13, and the utility model is cast as one by above four parts by die casting.
Be provided with successively on the jet body 1 the jet chamber 5 of spring and autumn, summer jet chamber 12 and winter jet chamber 11, an end in these three jet chambeies is closed, the other end is provided with seal cover 2; Control valve 15 comprises first control valve 14 and second control valve 9, the inwall of first control valve 14 is provided with air admission hole 4 in summer, one end of first control valve 14 is used to install the base of transition components 13, the other end communicates with second control valve 9, the end of second control valve 9 is provided with seal cover 2, metallic sheath 3 is bumped on the inwall of second control valve 9, be used for transition components 13 on the sealing ring in winter 8 match, metallic sheath 3 is made by rush-resisting materials such as stainless steel, aluminium alloy or copper alloys; Spring and autumn air inlet pipe 6 and winter air inlet pipe 10 be positioned at the both sides of second control valve 9, and be cast into one by a horizontal direction pipe and a vertical direction pipe, one end of two pipes is equipped with seal cover 2, the outlet side of spring and autumn air inlet pipe 6 with spring and autumn jet chamber 5 communicate, inlet end communicates with second control valve 9, winter air inlet pipe 10 outlet side with winter jet chamber 11 communicate, inlet end communicates with second control valve 9, spring and autumn air inlet pipe 6 and winter air inlet pipe 10 inlet end not on same straight line.
Referring to accompanying drawing 3, transition components 13 is installed on the control valve 15, on the transition components 13 rotary knob is housed, make transition components 13 be in summer during shelves when rotating rotary knob, thereby the sealing ring 8 in winter on the transition components 13 contacts with the inwall of metallic sheath 3 metallic sheath 3 sealings, and spring and autumn sealing ring 7 and first control valve, 14 inwalls contact and with its channel seal to the outstanding boss of central axis, and combustion gas can only 4 enter in the jet chamber 12 in summer by the air admission hole in summer; When transition components 13 is in spring and autumn during shelves, the boss that spring and autumn, sealing ring 7 broke away from first control valve, 14 inwalls, and winter, sealing ring 8 still contacted with metallic sheath 3 inwalls, thereby combustion gas by first control valve 14 and spring and autumn air inlet pipe 6 enter in the jet chamber 5 in spring and autumn; When transition components 13 rotates to winter during shelves, winter, sealing ring 8 broke away from the inwall of metallic sheaths 3, thereby combustion gas is by behind first control valve 14, a part enters in the jet chamber 5 in spring and autumn by spring and autumn air inlet pipe 6, another part by second control valve 9 and winter air inlet pipe 10 enter in the jet chamber 11 in winter.
